“…Expósito and Berbel (2017) and Grafton et al (2018) provided useful recommendations to policy makers in charge of promoting irrigation while preserving the environment. And political and social implications of the use of water in agriculture, as well as to what extent the lack of an agreed conceptual framework contributes to both unfair and inefficient use of water, were addressed by Boelens and Vos (2012), van Halsema and Vincent (2012) and Yunusa et al (2018).…”

“…Once again, the information available to the farmer will condition the use of these new indicators. Finally, remarks published by Yunusa et al (2018) and others, encouraging local authorities to finance the adoption of hi-tech irrigation in wide areas, must be taken with caution. If the adopted advances in irrigation refer to localized irrigation, deficit irrigation strategies or practices related to sustainable intensification, and they are accompanied by policies to avoid the Jevons effect, they should be effective in both improving the on-farm irrigation efficiency and the overall water saving in agriculture.…”

“…We used research and development expenditure ( lnRD ) to reflect R&D. As discussed by Falkenmark et al [28], the water available in a country or region is derived from the water cycle, which considerably affects total water resources. Water management problems are directly related to the population flow, and an important nexus exists between population and water resources [54]. Therefore, per capita water resource ( lnPERWATER ) has a significant impact on water scarcity.…”

The spatial relationship between water use efficiency and water scarcity has been widely discussed, but little attention has been paid to the impact of the pure technical and scale efficiencies of water use on water scarcity. Using input-oriented data envelopment analysis (DEA) and panel spatial Durbin models (SDM), the direct and spillover effects of different water use efficiencies on water scarcity from 2007 to 2016 in China were examined at the regional scale. The results show that the water use pure technical efficiency had significantly negative direct effects on water scarcity; however, the water use scale efficiency did not have a similar effect. The improvement in water use pure technical efficiency in one region could aggravate the water scarcity in neighboring regions through spatial spillover effects, but the same effect was not observed between the water use scale efficiency and water scarcity. Finally, we propose solutions to improve the water use efficiency to reduce the water scarcity.

For example, Namibia, largely a desert country, utilizes the available water resources to enhance food production by having a system of responsive and accountable governance ( 34 ).…”

Background: The UN Sustainable Development Goal (SDG) 2 (‘Zero Hunger’) aims to end all forms of hunger and malnutrition by 2030. Thus, a range of different strategies are needed to facilitate the achievement of SDG 2 to overcome challenges and enable synergies between various SDG targets. Objective: The aim of this review is to highlight Africa’s progress toward SDG 2, including targets, strategies, synergies and challenges. Methods: We scrutinized published research articles in peer-reviewed journals, UN reports and in-country Africa reports (between 2015 and 2020) that were relevant to the current topic. Results: Several hunger indicators are showing slow progress or even deterioration in Africa. The prevalence of undernourishment in the general population was 19.1% in 2019 and is expected to increase to 25.7% by 2030. Improvements in child stunting in several regions in Africa are slow, especially in sub-Saharan Africa where about 34% of under-fives were stunted in 2012 and 31% in 2019. In Eastern Africa, stunting prevalence decreased from 38% in 2012 to 34% in 2019. Major drivers of hunger are poor governance and state fragility, war and conflicts, increasing inequality, weak economic development, climate change, biodegradation – and now lately the Covid 19 pandemic – factors that all increase food insecurity. Conclusion: Africa is off track to reach SDG – ‘Zero Hunger’ – by 2030. Current efforts and progress are insufficient. Africa must champion the SDG agenda on a national, regional and global level to facilitate synergies to unlock the potential for reaching ‘Zero Hunger’ throughout the continent.

Analysis of the nexus between population, water resources and Global Food Security highlights significance of governance and research investments and policy priorities

Abstract: We suggest that to enshrine enduring food security, policies should prioritize (1) increased R&D investments that address farmer needs and (2) governance mechanisms that promote accountability in both research and production value chains. © 2018 Society of Chemical Industry.
